A STEP ABOVE
A STEP ABOVE
The all-new SR SUNTOUR AION38X is the ultimate all-mountain and hard-charging suspension fork at a price that will leave money left for a few extra shuttle laps or an extra battery. With robust 38mm stanchions and up to 180mm of travel this ebike ready fork goes even harder. Featuring our air EQ system and a sealed PCS damper, it makes for the easiest set-up and adjustments for the hardest and steepest trails. We also didn’t skimp on the details as we included integrated fenders, space for big tires and brake rotors, and fender mounting points all in a value-oriented package.
